Masland & Sons, Carlisle, Pa., a corporation of Penn- Sylvania The present invention relates to methods of weaving terry pile fabrics of the character of carpets and rugs, suitably of the wilton or velvet type.

This application has been divided and the claims relating to the fabric have been incorporated in a divisional application for Terry Weave, Serial No. 625,989, tiled December 3, 1956.

A purpose of the invention is to produce terry pile loops in a carpet having a stronger back.

A further purpose is to obtain a tighter weave and a stronger bind on the pile by increasing the crossings, using two spaced binder warp ends forming one bracket, and two spaced binder warp ends forming another bracket per dent, and placing pile warp ends and preferably also stuffer warp ends inside the brackets.

A further purpose is to selectively form terry loops or loops over Wires from the same pile warp ends within the brackets.

A further purpose is to form terry loops from one set of pile warp ends within the brackets and higher pile projections over another set of pile warp ends raised over wires, the terry loops providing cushions to support the higher loops.

Further purposes appear in the specification and in the claims.

In the drawings I have chosen to illustrate a few only of the numerous embodiments in which my invention may appear, selecting the forms shown from the standpoints of convenience in illustration, satisfactory operation and clear demonstration of the principles involved.

Figure 1 is a warpwise conventional wave diagram showing a weave according to the invention.

Figure 2 is a thread-in diagram of the weave of Figure 1.

Figure 3 is a warpwise conventional weave diagram showing a variation in the Weave of the invention.

Describing in illustration but not in limitation and referring to the drawing:

In my U.S. Patent 2,714,399, granted August 2, 1955, for Terry Pile Weaving, and my U.S. patent application Serial No. 369,815, filed Iuly 23, 1953, now Patent No. 2,750,969, for Terry Pile Weave, both incorporated herein by reference, I describe a procedure for terry pile weaving in which spaced binder warp ends woven together, constituting the only binder warp ends in the fabric, form a bracket and grip between them a pile warp end which is preferably slack tensioned as there described, and is held in the shed with the pile warp end down and the binder Warp ends up, the weft then inserted forcing the pile warp ends as they are gripped between the spaced binder warp ends up in terry loops as the weft is beaten up.

The present invention is designed to give a stronger back and desirably also very good support for pile projections which are formed over wires.

In accordance with the invention, the procedure for forming the terry loops may suitably be the same as that described in my patent and patent application, but there are two brackets of binder warps in each dent, and one 2,905,203 Patented Sept. 22, 1959 bracket is effective to form a terry loop at any upper weft.

The invention may be applied to a fabric in which the ends of a particular pile warp set sometimes form terry loops and sometimes form pile projections raised over wires, or can be applied where one pile warp set always forms terry loops and desirably also another pile warp set forms pile projections raised over wires.

Considering the form of Figure 1, I there illustrate pile warp ends 29, a binder Warp set 21, an opposed binder warp set 22, stuffer warp sets 23, upper wefts 24 and lower wefts 25 in a weave which may be similar to a conventional Wilton weave except for the thread-in, the number and character of the binder warp ends and the pile projections.

In this weave a wire 26 is inserted for each second shot, the wire suitably being of any of the well known types, such as a straight wire, a wavy wire, a cutting wire, a non-cutting wire, a flag wire, a high wire, a low wire, or any combination thereof. Pile projections 27 have been formed over the wires and bound behind the adjoining upper wefts in one area, while in another area as controlled by the jacquard, terry loops Z8 have been formed against the sides of the Wires, following the procedure of the aforesaid Hoeselbarth patent and patent application. Unlike the Hoeselbarth patent and patent application, however, there are two sets `of binder warps woven in opposition rather than a single set forming the bracket.

Figure 2 illustrates a thread-in which may suitably conform to the type of thread-in used in the weave of Figure l or the weave of Figure 3. I here illustrate splits 30 of the reed forming a single dent or course, the other dents or courses being suitably similar or with variations in thread-in immaterial for the present purpose. Spaced binder warp ends 21 (two in each dent) here form one bracket and spaced binder warp ends 22 (two in each dent) here form the other bracket, and when the particular bracket is up and the pile end is down the bracket functions as described in the Hoeselbarth patent and patent application to raise the terry loops. Binder warp ends 21 are always woven together and binder warp ends 22 are always woven together. Each bracket suitably contains stuffer warp ends 23 and pile warp end 20, permissibly with an additional pile warp end 20 later to be described.

The double brackets form an exceedingly firm weave. If two binder warp sets were used without double brackets it would only be possible to form terry loops at each fourth weft.

Figure 3 illustrates a modied weave having a separate set of pile warp ends 20' which are always woven over the wires to form pile projections 27 While the pile warp ends 20 always form terry loops 28.

When the wires are withdrawn the terry loops 28 under the higher pile projections 27 form a cushion to support the pile, thus greatly increasing the life of the fabric.

In view of my invention and disclosure, variations and modifications to meet individual whim or particular need will doubtless become evident to others 4skilled in the art to obtain all or part of the benefits of my invention without copying the process and fabric shown, and I, therefore, claim all such insofar as they fall within the reasonable spirit and scope of my claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. The method of weaving a terry pile fabric, which comprises threading in at least one pile warp end between a pair of spaced binder warp ends A per dent to form a bracket, and between another pair of spaced binder warp ends B per dent to form a second bracket, weaving the binder warp ends A in opposition to the binder warp ends B, and in the weaving forming a shed with a particular pile warp end in a dent down, all binder warp ends A up and all: binderwarp'ends B down, inserting a weft and forcing. the particular pile warp end upinto the pile in a terry loop as it is gripped between the spaced binder warp ends A in the same dent bybeating up the weft, forming a shed with the particular pile warp endin. thedent down, all binder warp.r ends B up and all` binder warp.y ends A down, inserting aweft and. forcing the` particular pile warp end up. into the pile ina terry loop as itis. gripped between the spaced binder warp. ends By inthe same dent by,` beating up the weft.

2. The method of claim. 1^, in. which the aforesaid pile warp. ends are slack tensioned.

3. The method of claim 1, in which stufer warp ends are also included in the brackets.

4. The method of claim 1, which comprises including an extra set of* pile warpl ends in the brackets. and weaving `the pile warp ends of the extra set over wires.

5. The method of claim 1, in which the pile warp ends are Woven over wires at intervals.

6. The method of claim 1, which comprises including7 an extra set of pile warp ends inthe brackets and weaving the eXtra set of pile warp ends over wires, the terry loops forming cushion loops under the loops formed over the wires.
